Allwinner R818

Cost-efficient 64-bit intelligent hardware processor

Overview

Allwinner R818 is a powerful processor features with quad-core Cortex-A53 CPU operating with frequency up to 1.6GHz. It integrates with GE8300 GPU, H.265 4K30 video decoder for UI rendering, H.264 1080P60 encoder for media player, and 13MP camera ISP for video VOIP. Allwinner R818 also integrates with two ADCs for dual-mic voice solutions, DMIC and I2S for multi-mic solutions, and two DACs for stereo audio speaker. Moreover, Allwinner R818 supports IR transmission and IR reception for intelligent control of smart home devices. The above features together make Allwinner R818 a cost-effective solution for smart speakers with screen.
